Thisl invention Vrelates Yto a coin controlled water meter inwhich the waterconsumption is` indicated at all'times.

An object of the invention is to provide a simplied and reliable` form of construction particularly designed for use in connection with a membrane valve controlling the water supply.

' Afurther objectof the invention is to provide a construction in which the water meter` controls a revolving plate orlbar which in turn controls the valve controllingthe' water supply.

With the above and other objects in-view which will become apparentv from the detailed description below, the invention is shown inthe drawings in which:

'indicated by the arrowv 81. VAcoupling 4 connects one end of the water-meter to the valve housing.

The control means for operating the valve 5 will now be described. This comprises a flat plate '2 secured to the vertical shaft 3 Which is rotatably mounted upon the bracket I3 which in turn is secured at one end to the waterlmai'n 6 and at the other end to the coupling 4; The' Shaft 3 is rotatedby the Water meter by means of thegears I4 and the shaft, {I thereby rotating the plate 2 inv accordance with the consumption of water in the house.

A small aperturev I6' is'provided in the plate 2 asshown in--Fig. Z'Which is designed to cooperate With a valve'- controlling rod II. The rod II is ixed to a valvev` I8-which controls the flowV of water' into the space between the rod II andy theI housingv 48v and thence through the pipe 6I to a point in backfof the wall 62 of the valve 55.'V When the control rod--I'I is vurged down;v

wardlyY by the plate 2-`which1occurswhen thel top ofn'the rod I1 isjnot seated'inthe aperture` I6', then Vthe valve I8 is also urged downwardly' thereby permittingA` the water to flowV in the manner indicated'throughthe pipe 6I to a point in back of the wall 62. When the valve I8V is in suchposition then the/membrane I9 is also open and the/'water will flow'f'rom the water main 6 to the point 645 at the other'sideof the Valve 5 as indicated'by the arrow 63in Fig. 1 between the wall 6-2 andthe membrane I9.` Also whenV the membranev is open the water'willfflow through the small opening 20 provided in the membrane I9 into the space 2| VbelowV the membrane and through'a passage 59 intothe space 60 and then passes the Vvalve I8 tothe pipe 6I.

However; when the control, rod I 1 is urged upwardly into the aperture I6 by means of the spring 65 the valveL I 8L closes the water flow through the pipe 6l. Then the pressure' in theA space 60 and the space 2| will be equalized to the water pressure in the4 main 6i and in such case the membrane I9 willbe urged upwardly' against the lower edge of theV wall 62 and the flow of Waterwillfbe/stopped.

af membranel lfwhich is usually made of rubber.

The other cooperating elements of the valve will be described below.

Also controlling the water'main 6 is a stopy cock V'Iland 'theU ,direction of :dow of water is When thel control rod' II` is forced out of the recess I6 and thereby forced downwardly', the Water supply willv again be opened. This action of the control rod I'Il is brought about by the coin controlled mechanism shown particularly in Figs. 5 and 6.

The quantity of Water supplied for a particular coin is fixed by Aone revolution of the plate 2.' A-lso` the amount of water supplied may be' a'd'-l justed to any desired quantity by providing suitable gearing between the shaft 3 and the Water meter transmission II.

The coin control for the valve controlling rod I1 will now be described. This coin control is particularly shown in Figs. 5 and 6. A channel 22 for the coin is located between the guide bars 23 and 24 which in' turn' 'are located-'between the front plate 25an'd theback plate 28. `Upon dropping a coin in the channel 22 such coin will come to rest upon a xed bar 21 and one arm of a double-armed lever 28 pivotally mount- Y ed on a pin 29 fixed to the back plate26. The

-on the top of the Vcontrol rod I1. The slide 51 is connected'to the plate 12 by a Spring in the other arm of the lever 28 ispivotally connected to the control rod I1 by means of apivotl 30. The lower edge of the arm of the lever 28 cooperating with the coin is bent in such a manner that the coin may be held thereby. A spring 3l bears against the lower edge of the coin arm of the lever 28 and tends to raise such arm upwardly of the plate 2 thereby cuttingoi the supply ofV water through the val. ve l 5 `in the manner above described. f l

In order to secure `a new Supply of water and removethe .control rod I1y from the recess I6 as shown in Fig. .5, the button 32-on the slide 33 is pressed inwardly. Theslide 33 contacts the coin 42 with its lower. front -bevelled edge and `pushes the coinagainst the coin armof the lever 28 vthereby pivotingrthe lever 28 about the pin 29. This pivoting of the. lever 28 causes a downward movement lrif/the control rod I1 thereby releasing the plate,2. When theY space between the Acoin armof.the lever 28.and the into acoin box, not shown.

bar 21 .is sufficiently wide thecoin will drop downl The downward movement o f the valve control rod I1 is just suiicientfto releasethe plate 2 and in the mannerabove described themembrane I9 will be opened in the, valve 5an d.the water p assing throughfthemeter will revolve the driving element I'Sand therebyremove the recess I 6 from alignment with thecontrol rod I1.V The mem-V brane I9 of the yvali/ e5 will therefore remain Open until the plate ,2 .makesa `complete revolution when the recess, I 6 -5will `be again aligned with the control'rod I1. s

`The means 'for returning'theslide 33 to its original position afterbeing` depressed, is shown in Figs. 5 and .6. This'comprisesa bracket mem.v ber 36 which Ysecures..a tubula'r element 31 to the plates andY 25.l The tubular element 31 houses a spring 38 .which at onef end, the left-A hand end, as shown'in Fig. 5, contacts the closed end of the tubular `element 31 and at the other end bears against a`disk'39 which. is xed to a rod 40 carried .by.t lie .slide, .33. 'Ihe rod 48j projects atl right anglesto the slide 33'and extendsy through a groove 4I provided Vinthetu-bular element 31. Upon depressionofthe-'button 32fwi`th a consequent movement of the slifde 33y to theleft as shown in Fig "5,'the spring 3.8 will becompressed land upon release .of .the button 32 suchV spring vacting against'thegdis'k .'38 will returnA Vthe slide 33 to itsor'iginal position. Y

In' Figs. 3 and`4 a modified construction for'v theV plate 2 is shown in `Whiclrtlbere `is provided a cylinder42 `rotatin'g about`a horizontal axis.
